Giant panda Tai Shan eats bamboo in his enclosure on February 1, 2010 at the Smithsonian's National Zoo in Washington. The National Zoo has announced that beloved panda Tai Shan will be sent to China on February 4. Tai Shan, once dubbed 'butterstick' for his tiny size, was born there in 2005 to Mei Xiang and Tian Tian, themselves gifts from China. A stipulation of the gift is that all cubs must be sent to China. AFP PHOTO/Tim Sloan (Photo credit should read TIM SLOAN/AFP/Getty Images)
